What source of energy does the world need in the near future?

SOLAR ENERGY

1.Shortage of energy is major world problem and experts predict that the present rate of increase in energy use could exhaust the supply of fuels in the twenty-first century. What the world needs is a source of perpetual energy.

2.Potentially, we have a source of perpetual energy shining down on us. The sun. On clear day in the tropics, the intensity of solar energy can be more than a kilowatt per square metre at mid-day. That amount of energy falling on an area of sixty-four square kilometres is about as much as the whole of the British electricity generating system produces.

3.There is no charge for the energy that flows so freely from the

sun.

4.Unfortunately its collection and storage can be both difficult and expensive. Some form of storage is necessary because the sun's rays do not reach us on cloudy days or at night. None the less, solar energy is now an economic and practicable solution and is widely used in many countries.

5.It is possible to convert solar energy directly to electricity by the use of photoelectric cells but for most practicable purposes this is too expensive a way to produce electricity. Today’s solar energy systems are of two main types, based on the flat plate collector and the focusing

collector. The flat plate collector is simpler and cheaper. In its simplest form, the sun's rays fall onto a panel.

Pipes carrying water are embedded in the panel. The sun heats the water, which is then available for use. Modern flat plate collectors are carefully designed to absorb the maximum possible amount of energy and to prevent heat loss to the surroundings. They are mainly used for the provision of domestic hot water. They are commercially available and are in use in many countries including Australia, Japan, Cyprus, Brazil and Israel.

6. Focusing systems enable a much higher proportion of the sun’s energy to be trapped and also produce much higher temperatures. Temperatures up to 4,000˚С have been reached in the solar-powered Odeillo furnace in the Pyrenees. The principle has been known for along time, Archimedes used it in 212 B.C. when he used focusing mirrors to set fire to the Roman fleet.
